Description

[Technical Field]

[0001] The present invention relates to a furniture drive for driving a movable furniture part, which comprises at least one electric motor, at least one actuator for applying a force to the furniture part to be driven, which is preferably movable back and forth between two end positions, and a transmission interposed between the electric motor and the actuator.

[0002] Such furniture drives with electric motors are already known in the prior art. They enable, for example, automatic opening of furniture parts. Servo motors with relatively low rotational speeds are typically used. The furniture drives have a relatively large structural form and, in the case of a flap bracket, are externally fitted onto the flap bracket.

[0003] In recent years, efforts have been made to reduce the structural dimensions of furniture drives, so that they can be arranged concealed, in particular in the walls of furniture.

[0004] For this purpose, a flat furniture drive and a suitable electric motor are required.

[0005] The object of the present invention is to provide a furniture drive that is constructed particularly flat.

[0006] This problem is solved by the features of claims 1 and 15.

[0007] According to the invention, the electric motor is configured as a disk motor.

[0008] The disc motor can be made particularly flat, which makes it possible to achieve a particularly flat furniture drive.

[0009] The coils and magnetic poles in a disk motor can be positioned relatively far outward, so the torque to rotational speed ratio is relatively high compared to other configurations.

[0010] In a disk motor, at least one rotor and at least one stator are arranged at least partially axially offset from one another, like two axially offset disks.

[0011] In a preferred embodiment, at least one coupling device, preferably a belt, particularly preferably a toothed belt and / or a gear, is provided, and an electric motor, preferably a belt pulley coupled to the shaft or shaft of the electric motor via the coupling device, is connected to the transmission device.

[0012] Particularly preferably, the coupling device extracts the torque of the disk motor from between the coils and / or magnetic poles arranged in the stator or rotor and / or from a central shaft preferably supported on the stator or rotor, in which case the shaft preferably has a smaller diameter than the stator and / or rotor.

[0013] By using a coupling device, in particular a belt or gear, the sound transmission from the electric motor to the transmission is reduced even at high rotational speeds. The coupling device can additionally function as a first transmission stage.

[0014] Particularly preferably, the first gear stage, and preferably all gear stages, are oriented eccentrically relative to the stator and / or the rotor and / or the central axis and / or the motor shaft.

[0015] It may be specified that the connecting device consists at least in part of a sound-deadening material, preferably the sound-deadening material of the connecting device is rubber, natural rubber, plastic, or an open-cell or closed-cell material, preferably polyurethane elastomer, rubber foam, silicone foam, EVA foam or PE foam, and / or neoprene.

[0016] The sound deadening material, especially neoprene, can be provided with glass fiber tension and special woven fabrics to reduce noise and avoid contamination from rubber abrasion.

[0017] In a particularly preferred embodiment, the coupling device is configured as a belt.

[0018] In particular, the belt and the electric motor can be arranged in substantially the same plane, so that the belt does not make an additional contribution to the width of the furniture drive.

[0019] The belt may be applied or may be applied to a shaft inside the electric motor or to a belt pulley connected to this shaft. In particular, the shaft does not have to extend across the width of the electric motor.

[0020] The belt may be arranged or may be arranged partially in an intermediate space between at least two coils and / or magnetic poles arranged in a stator of an electric motor, in particular configured as a disk motor.

[0021] Preferably, the first section of the belt is arranged in a first intermediate chamber and the second section of the belt is arranged in a second intermediate chamber different from the first intermediate chamber, thereby allowing at least one coil and / or at least one magnetic pole to be arranged between the first and second sections of the belt.

[0022] The belt can thus be guided from the inside to the outside of the electric motor.

[0023] Alternatively, the belt can be applied to the outer diameter of the electric motor, in particular to the outer diameter of the rotor of the electric motor.

[0024] According to a preferred embodiment, the at least one electric motor is configured as a brushless motor, in particular as an EC motor with at least one electronic control unit for commutating the magnetic field. Brushless motors have the advantage of being quieter and less maintenance-intensive than brushed motors.

[0025] A brushless motor may be understood as an electric motor in which no current is transmitted to the rotor. Typically, only passive elements, such as permanent magnets, are located on the rotor. The current-carrying elements, such as coils, are located on the stator. The magnetic field is typically commutated using an electronic control unit (EC motor).

[0026] The abbreviation "EC" in "EC motor" stands for "electronically commutated," which applies to electronically controlled magnetic field commutation.

[0027] In a preferred embodiment, the electric motor can have a width of less than 16 mm, preferably less than 10 mm, particularly preferably less than 8 mm, so that the electric motor is made particularly flat.

[0028] "Width" means in particular the overall width of the electric motor, including any shaft for the power output, which can therefore be of generally flat design and can be housed in a preferably generally flat casing.

[0029] It may be specified that the electric motor has a diameter of less than 90 millimeters, preferably 80 millimeters or less.

[0030] The electric motor preferably has a holding moment and / or maximum torque of 0.3 Newton meters or less when applied with a voltage of 50 volts or less.

[0031] The disk motor is in the preferred embodiment configured as an axial flux motor, so that the magnetic flux is directed in the axial direction.

[0032] The disc motor can preferably have a rotor with at least four, particularly preferably exactly eight, magnetic poles, although fewer or more magnetic poles are also conceivable.

[0033] The rotor may be shaped like a disk, with the magnetic poles located on one side of the disk.

[0034] The disc motor can preferably have a stator with at least three, particularly preferably exactly six, coils, although fewer or more coils are also conceivable.

[0035] The stator may be disk-shaped and may surround the rotor on both sides. A coil, preferably coreless, is arranged on the stator. Furthermore, the coil may be provided with a magnetic flux guide, preferably made of a sintered material, which guides the magnetic flux.

[0036] In a preferred embodiment, it is specified that the rotation axis of the electric motor is oriented substantially parallel to the rotation axis of at least one element, preferably all elements, of the transmission, so that an electric motor configured flat in the direction of its rotation axis does not enlarge the furniture drive.

[0037] Preferably, the furniture drive may have at least one housing, in which the transmission and the electric motor may be arranged.

[0038] It may be specified that the furniture drive has at least one support device via which the electric motor is supported in and / or on the casing, and that the at least one support device includes at least one damping element made of sound-deadening material, thereby also reducing sound transmission from the electric motor to the casing.

[0039] Preferably, in this case, it is specified that the at least one support device has at least one support part connected to the electric motor, and preferably this support part is formed as a steel shaft, rivet or pin.

[0040] At least one first damping element and at least one second damping element may be arranged on the support part, where the first damping element is arranged to reduce sound transmission between the electric motor and the casing in a first spatial direction, and the second damping element is arranged to reduce sound transmission between the electric motor and the casing in a second spatial direction transverse to the first spatial direction, where it may be specified that the first damping element and / or the second damping element are formed as a damping disk or a damping sleeve.

[0041] In particular, two or more, preferably three, support devices may be provided for supporting the electric motor in and / or on the casing.

[0042] In a preferred embodiment, at least one transmission device is provided connecting the gearing to the actuator, which transmission device preferably comprises at least one lever.

[0043] In one embodiment, the electric motor and the transmission are arranged in a first casing, and the actuator is arranged in a second casing structurally separated from the first casing, preferably arranged such that the two casings are arranged one above the other in a connected state, substantially in a common plane, so that the width of the furniture drive is not increased.

[0044] At least one lever arrangement may be provided, pivotally connecting the actuator to the casing.

[0045] At least one mechanical energy accumulator may be provided, which can apply a force to the actuator to compensate for the weight of the furniture part to be driven.

[0046] The actuator may be located substantially completely within the casing in the first end position.

[0047] Suitably, the casing is specified to have a maximum width of less than 18mm, preferably less than 16mm.

[0048] The furniture according to the invention, preferably an upper cabinet, comprises at least one movable furniture part, preferably in the form of an upwardly openable flap, and at least one furniture drive according to any one of claims 1 to 14, wherein the furniture part is movably supported on the furniture via the at least one furniture drive.

[0049] In a preferred embodiment, the furniture comprises at least one wall, and the casing of the at least one furniture drive is inserted substantially completely into a recess in the wall.

[0050] Further details and embodiments are shown in the drawings. [Brief explanation of the drawings]

[0052] 1 and 2 show a piece of furniture 25 in the form of an upper cabinet, which comprises a movable furniture part 2 in the form of an upwardly openable flap and a furniture drive 1, wherein the furniture part 2 is movably supported on the furniture 25 via the furniture drive 1.

[0053] The furniture part 2 is pivotable about a horizontal axis 31 .

[0054] The furniture 25 may have a back wall 28, a top surface 29 and a bottom surface 30, as in the illustrated example.

[0055] The furniture 25 may have a wall 26 , in which case the casings 3 , 21 of the furniture drive 1 are each inserted substantially completely into a recess 27 in the wall 26 .

[0056] The casing 3, 21 suitably has a maximum width 24 of less than 18 mm, preferably less than 16 mm.

[0057] An electric motor 4 is arranged in a casing 3, which is only shown diagrammatically in Figure 2. In the casing 21, in particular, an actuator 7 is arranged pivotably, which is connected or connectable to the furniture part 2.

[0058] Not all furniture drives 1 need to be equipped with an electric motor drive unit: in the example shown, only one of the furniture drives 1 has an electric motor drive unit.

[0059] Alternative configurations of furniture are also conceivable in which the furniture drive 1 according to the invention is used.

[0060] Figure 3 shows a furniture drive 1 for driving a movable furniture part 2, which has at least one electric motor 4, at least one actuator 7, preferably movable between two end positions, for applying a force to the furniture part 2 to be driven, and a transmission 8 interposed between the electric motor 4 and the actuator 7.

[0061] In this case, at least one belt 9, preferably a toothed belt, is provided, via which the electric motor 4, preferably a shaft 11 of the electric motor 4 or a belt pulley 12 coupled to this shaft, is connected to the transmission 8. In particular, the belt 9 is connected to a second belt pulley 10 of the transmission 8.

[0062] The belt 9 can be tensioned by means of a belt tensioner 13, which is preferably pivotable, and which can engage the belt 9, for example, by means of a roller.

[0063] Alternatively or additionally, the electric motor 4 may be slidably supported, so that the belt 9 can be tensioned by sliding of the electric motor 4 .

[0064] Instead of the belt 9, another coupling device may be provided between the electric motor 4 and the transmission 8, for example a gear or a worm 38 (see Figures 10a to 11b).

[0065] The electric motor 4 is configured as a disc motor 6 .

[0066] The electric motor 4 and the transmission 8 may be arranged in the illustrated first casing 3, and the actuator 7 may be arranged in a second casing 21 structurally separated from the first casing 3, preferably in this case the two casings 3, 21 being arranged one above the other in a substantially common plane when connected.

[0067] At least one transmission 20 is provided connecting the transmission 8 to the actuator 7, the transmission 20 having at least one lever. Alternative configurations of the transmission 20 are also conceivable. In particular, the transmission 20 is connected to the transmission 8 via a non-circular member 19.

[0068] At least one lever arrangement 22 is provided which pivotally connects the actuator 7 to the casing 21. In the specific case, the lever arrangement 22 forms a seven-joint arrangement.

[0069] At least one mechanical energy accumulator 23 is provided, which can apply a force to the actuator 7 to compensate for the weight of the furniture part 2 to be driven. The mechanical energy accumulator 23 can comprise one or more compression springs 34.

[0070] A force transmission lever 35 may be provided to transmit the force stored in the mechanical force accumulator 23 to the actuator 7 .

[0071] Furthermore, a force adjusting device 33 may be provided, which is preferably accessible from one end face of the casing 21, by means of which the spring preload of the spring 34 can be adjusted.

[0072] In a first end position, which corresponds to the closed position of the furniture part 2, the actuator 7 is arranged substantially completely within the casing 21.

[0073] The transmission 8 includes multiple transmission stages 32, which may incorporate overload clutches and / or freewheel clutches. The transmission stages 32 may be realized by gears 18 of different sizes.

[0074] Figure 4a shows an electric motor drive unit in a perspective view, which comprises a casing 3 without a casing cover, a transmission 8 and an electric motor 4. Figure 4b shows a corresponding side view.

[0075] The rotation axis of the electric motor 4 is oriented substantially parallel to the rotation axis of at least one, preferably all, elements of the transmission 8, in particular the transmission gear 18. In such an installation state, the axially flat electric motor 4 requires little space in the width of the furniture drive 1, thus making it possible to realize a flat furniture drive 1.

[0076] FIG. 5 shows parts of the casing 3 not shown in FIGS. 4a and 4b, as well as the transmission 8 and the electric motor 4, from the other side relative to FIGS. 4a and 4b.

[0077] FIG. 6 shows the casing 3, the transmission 8 and the electric motor 4 in an exploded view.

[0078] FIG. 7 shows the casing 3 closed.

[0079] Figures 8a to 9b show the transmission 8 and the electric motor 4 without the casing 3. Figures 8a and 8b show the transmission 8 and the electric motor 4 from a first side, and Figures 9a and 9b show the transmission and the electric motor 4 from a second side.

[0080] 8b and 9b show the transmission gear 18 in an unobscured manner, so that the design of the transmission stage 32 can be seen.

[0081] The transmission 8 reduces the rotational speed. The fastest rotating part, i.e. the electric motor 4, is the noisiest due to its high rotational speed and should be isolated.

[0082] The reduction of sound transmission to the transmission 8 is achieved in this embodiment in that the first transmission stage is formed by the belt 9. The belt 9 may at least partly consist of a sound-deadening material, preferably the sound-deadening material of the belt 9 is rubber, natural rubber, plastic, or an open-cell or closed-cell material, preferably a polyurethane elastomer, rubber foam, silicone foam, EVA foam or PE foam, and / or neoprene.

[0083] The reduction of sound transmission to the casing 3 can be achieved in that the furniture drive has at least one support device via which the electric motor 4 is supported in and / or on the casing 3, and the at least one support device can include at least one damping element made of sound-deadening material.

[0084] 10a-11b show an alternative embodiment in which the first gear stage is realized by a worm 38. A disadvantage of this embodiment is that sound from the electric motor 4 can be transmitted to the gear 8 rather via the worm 38.

[0085] 10a to 11b, the rotation axis of the electric motor 4 is not oriented parallel to the rotation axes of the elements of the transmission 8. In order to achieve a flat furniture drive, the electric motor 4 must have a small diameter.

[0086] 12a and 12b show an embodiment of a flat disc motor 6 according to the invention, in which a rotor 39 and a stator 40 are substantially disc-shaped and are arranged axially offset from one another.

[0087] As can be seen from the exploded view of Figure 12b, eight magnetic poles 17 are arranged on the rotor 39. However, other numbers of magnetic poles 17 are also conceivable.

[0088] The stator 40 is provided with a coil support 43, on which six coils 16 are arranged, although other numbers of coils 16 are also conceivable.

[0089] In this embodiment, the coil 16 is formed coreless.

[0090] Axially offset from each coil 16 is a flux guide member 42. The flux guide member 42 has substantially the shape of a disk segment provided with a hole.

[0091] The flux guide member 42 is made of a sintered material.

[0092] The magnetic flux guide member 42 is used to guide the magnetic flux.

[0093] Coil covers 41 are positioned above the coil 16 and flux guide members 42, preferably with a unique coil cover 41 provided for each coil and flux guide member pair.

[0094] The disk motor 6 is configured as an axial flux motor, and therefore, due to the arrangement of the coil 16, the magnetic flux extends in the direction of the rotation axis of the disk motor 6.

[0095] The disc motor 6 can be configured brushless, since only passive magnetic poles 17 are arranged on the rotor 39. Preferably, the disc motor 6 is configured as an EC motor (EC stands for "electronically commutated") with an electronic control unit for commutating the magnetic field.

[0096] The coils 16 are controlled via energy and signal lines 36, which are not shown in Figures 12a and 12b (but are shown, for example, in Figures 4a and 5). Furthermore, the electric motor 4 may be provided with sensors, such as Hall sensors, for example, to determine the position of the rotor 39.

[0097] The rotor 39 and the stator 40 are connected to each other via a bearing 37 .

[0098] The output shaft 11, on which for example a belt pulley 12 is arranged, may protrude axially from the rotor 39 and / or the stator 40, as shown in Figures 3 to 8b. The belt 9 must therefore be arranged axially offset relative to the electric motor 4. A disadvantage of this embodiment is that the belt 9 contributes to the minimum width of the furniture drive 1.

[0099] In the embodiment of FIG. 13, the belt 9 and the electric motor 4 are arranged substantially in the same plane.

[0100] In particular, the belt 9 is applied or can be applied to a shaft 11 inside the electric motor 4 or to a belt pulley 12 connected to the shaft.

[0101] The belt 9 is arranged in part in an intermediate space between at least two coils 16 arranged in a stator 40 of the electric motor 4 configured as a disc motor 6. The belt 9 can therefore be guided from the inside of the electric motor 4 towards the outside onto a second belt pulley 10.

[0102] In particular, a first section of the belt 9 is arranged in a first intermediate chamber and a second section of the belt 9 is arranged in a second intermediate chamber different from the first intermediate chamber, so that one coil 16, in particular together with a coil cover 41, is arranged between the two belt sections.

[0103] The electric motor 4, and in particular the disc motor 6 shown in Figures 12a to 13, can have the following characteristics: a width of less than 16 millimeters, preferably less than 10 millimeters, particularly preferably less than or equal to 8 millimeters, and / or a diameter of less than 90 mm, preferably 80 mm or less, and / or Preferably, a holding moment and / or maximum torque of 0.3 Newton metres or less when a voltage of 50 volts or less is applied.
